Hi Mike,

hmm, how is this supposed to work. If it is the kernels job to
send them, are recent kernels then broken?
If I telnet into the board and then resize my x-terminal, all
works as it should. I assumed the telnet daemon made sure to
send the SIGWINCH but I havn't checked.

Perhaps the serial console is a special case that dosen't get SIGWINCH?
